NEWSPAPER-WRAPPING MACHINE.

SPECIFICATION forming part of Letters Patent No. 517,441, dated April 3,1894.

Application filed October 7J 1893. Serial No. 487,502. (No model.)

chines, fully described and represented in the following specificationand the accompanying drawings, forming a part of the same.

rlhe object of the present invention is toA provide an improved wrappingmachine, and

- especially to provide a simple and rapid machine of that class used inwrapping newspapers and other publications for mailing and generallyknown as newspaper wrapping machines.

. The principle upon which a machine embodying the present inventionvoperates is that of first advancing the paper or other article to bewrapped to the required point with the Wrapper overlapping its leadingend and with the iiap of the wrapperprojecting behind the papersufficiently to overlap upon the layer of wrapper for pasting, and thenreversing the direction of movement of the paper and turning over andpressing down the Hap of the wrapper so as to secure the overlapping andpasting of the ia'p upon the layer of wrapper on the paper as thereversed paper is advanced. In another application, Serial No. 470,167,filed April 13, 1893, I have described and claimed broadly a machinecon; structed to operate upon this principle employing means of anysuitable form, such as tWo pairs of oppositely driven rotating segmentsor` a pair of rolls driven alternately in opposite directions, foradvancing and reversing a paper and wrapper, in combination with a flapturner for turning over the ap of the wrapper, this iiap turnerpreferably consisting of a roll past which the reversed paper is fed andupon opposite sides of which the paper passes during its movement inopposite directions. The present invention relates to a machine of thisgeneral construction in which the roll forming the flap turner coaotswith one of the rolls or segments in the advance movement of the paperand with the other roll or one of the oppositely driven segments in thereverse movement.

It is obvious that different constructions of feeding rolls or segmentsand devices for driving the same may be used, and that the roll formingthe flap turner may be driven only by friction from the rolls orsegments with which it coacts or positively, and in the latterv casethat different means may be used for driving this roll. I prefer to use,however, a pair of feeding rolls driven in opposite direc` tions so asto advance and reverse the paper 6o by the same feeding surfaces andactuated by a sliding rack operated by a cam or other suitable means andgeared with one or both of the feeding rolls so that as this rack isreciprocated the rolls are positively driven in opposite directions. Itis preferable, although not essential in all constructions, that guidesshould be used for guiding the end of the reversed paper to the oppositeside of the flap turner. These 7o guides may be of any suitable form andany suitable means for withdrawing them from the path of the paper as itis advanced to the feeding rolls may be used, but I prefer to use aseries of fingers so constructed as to form spring fingers exerting ayielding press: ure upon the paper only sufficient to secure themovement of the reversed paper in the proper path and withdrawnpositively from the path of the next advancing paper.

The wrappedvpaper may be delivered di.- rectly from the feeding rollsand flap turner forming the wrapping mechanism, the ,f iap turner andfeeding roll with which it coacts., in reversing the paper operating topositively 8 5 advance the paper and press down and secure the wrapperafter the paper has passed out of the control of the feeding rolls, butI prefer to combine with the wrapping mechanism pressing and deliverydevices of any 9o suitable construction, such as feeding rolls or tapesby which the paper is received from the wrapping mechanism andthewrapper held pressed down for some time before final delivery so as toallow time for the paste to set, 95 the securing of the wrapper thusbeing assured with machines operating at 'very high rates of speed. Thepapers and wrappers, or either of them, may be fed to this wrappingmechanism by hand, or any suitable roo feeding device for automaticallyadvancing the papers and wrappers to the feeding mechanism in propertime,together or separately may be combined therewith, and the papersmay be previously folded to the size desired or folded, eitherpartiallyor wholly, by mechanism embodied in and forming a part of themachine. The wrapping mechanism may be combined with any of the ordinaryforms of folding and delivery mechanisms now in use in folding machines,or combined printing and folding machines, so that the paper may beprinted, folded, wrapped and delivered by a single machine, the wrappingmechanism herein shown being of suiiicient capacity to be applicable tomodern web printing machilies.

The delivery of the papers and wrappers to the wrapping mechanism inproper position may be secured in any suitable manner, but I prefer tofeed the wrapper downward in the line of movement of and in front of thepapers as they are advanced to the wrapping mechanism, so that eachadvancing paper will engage the wrapper upon the desired line and carryit with it to the wrapping mechanism. The wrappers may previously be cutto the desired size and fed to the wrapping mechanism as sheets, but itis preferable to feed the wrappers from the web and sever them in themachine.

Fasting devices for the wrapper are preferably added, and the paste maybe applied to the first layer of wrapper upon the paper, or to the looseend of the wrapper prior to or at any desired time during the operationof wrapping, but it is preferable to apply the paste to the first layerof wrapper upon the paper, the movement of the wrapper with the pastethus being reduced.

In the accompanying drawings forming a part of this specification, thereis shown for the purpose of illustration, a complete, independent,newspaper or pamphlet wrapping machine of the general construction abovedescribed, which will be found a convenient and eihcient embodiment ofthe present invention, the previously folded papers or pamphlets beingfed from a pile and the wrappers from a web, and a detailed descriptionof the same will now be given, and the features forming the inventionspecifically pointed out in the claims.

In the drawingsz-Figure l is a central vertical, longitudinal section ofthe machine. Figs. 2 and 3 are partial views similar to Fig. l showingthe wrapping mechanism in different positions during the operation ofwrapping,-and Fig. 4 is a horizontal section on the line 4 of Fig. 1.

The frame of the machine may be of any suitable construction forsupporting the operating parts. At the rear or delivery end of themachine are mounted the reversible feeding rolls C, D, which so far astheir action upon the paper is concerned, may have continuous surfaces,but are preferably formed of a series of disks or cut away to accommodate other parts of the wrapping mechanism. These rolls are preferablyrubber faced, milled or otherwise roughened so as to give a good gripupon the paper. The shafts of these rolls C, D carry inside the framegears 10, 1l and are rotated in opposite directions by rack bar Eprovided with racks at opposite sides engaging said gears, said rack barsliding at one end in a suitable guide l2 in the frame of the machineand at its opposite end being provided with a slot threaded on shaft 13,and engaged by two bowls 14,15, running in a cam groove a on the face ofa cam disk F on shaft 13, so that by rotation of the cam disk F the rackE is reciprocated in the guides 12. Iufront of the rolls C, D, and onthe side at which the paper is fed to the rolls, the flap turner b isplaced, this liap turner l? consisting of a roll mounted to rotate inthe frame and driven from the main driving shaft S by gears 16, 17. Thisflap turning roll b is located in position so as to coact with the rollC in feeding in the paper to be wrapped, as shown in Fig. 1, and tocoact with the roll D in advancing the reversed paper, thus operating toaid in feeding the papers to the rolls C, D, and advance and deliver thepaper after it has left the grip of the rolls C, D, while it pressesdown the iiap of the wrapper with suiiicient pressure to secure thewrapper by pasting. The reversible feeding rolls C, D, and the Hapturning roll b therefore form a complete wrapping mechanism and thewrapped paper may be finally delivered directly therefrom. In a machineof high ca pacity, however, it is evident that the pasted portion of thewrapper is pressed between the rolls b, D but a short time and it ispreferable that means should be provided by which the wrapper shall beheld pressed down a longer time, so as to insure the setting of thepaste to properly secure the wrapper. It is preferable, therefore, tocombine with this wrapping mechanism pressing and delivery devices towhich the paper passes from the rolls b, D and by which the wrapper isheld pressed down until the paste has set and the paper then finallydelivered. These pressing and delivery devices may be of any suitablecon struction, and the roll D may be used as part of said pressing anddelivery devices, orthe delivery devices may be separate from andindependent of the roll D.

I have shown a simple and efiicient construction in which feeding rollsor tapes are used, arranged as follows:-A series of belts c are ledabout belt rolls or pulleys2l mounted below the flap turner b andcarried by adjustable arms 22 so as to be adjustable to vary theposition of the belts and secure the proper grip upon papers ofdifferent thicknesses. The belts c are led from belt rolls 21 to rolls23 by which they are driven, thence to rolls 24 and returned to the beltrolls 2l over adjustable tension rolls 25. The series of belts d are ledabout small rolls 1 above the flap turning roll b, then downward aboutthe latter, thence along with the belts c under the IIO rolls 23, thenaround rolls 27 opposite to and driven from rolls 24, returning aroundadjust-able tension rolls 28. The feeding belts Vc, CZ, therefore,continue the pressure upon the wrapper from the time when it is turnedback by the flap turning roll b and pressed between it and the roll Dand continue this pressure for a suitable time so as to hold the wrappedpaper in form and under pressure until the paste has fully set, anddeliver the wrapped paper at the end of the machine, although it will beunderstood that these belts may be arranged so as to deliver directlydownward from the wrapping mechanism, or at any other desired point,although the construction shown is preferable, as it gives a long runfor the belts.

It will be found that the construction thus far described is efficientand that the papers will generally be carried backward properly underthe tiap turner b, especially if the papers be of such thickness as tobend readily, but in order to assure absolute certainty of action,however,.there is preferably used with thick rigid papers a series ofguides which operate to positively guide the rear end of the reversedpaper downward and below the flap turner b. These guides may beconstructed in any suitablev manner, but as shown consist of a series ofspring fingers f which are ear ried by a rock shaft 39 actuated to raisethe guides out ofthe path of the paper as it passes to the rolls C, D,by a crank arm 40 carried by the shaft and spring pressed by a spring 4lon rod 42 mounted on the outside of'one of the side frames,'the shaftbeing rocked-in the opposite direction to press the guides downward atthe proper time to act on the vleading end of the reversed paper by acrank arm 43 on the shaft 39 carrying a bowl which runs on a cam wcarried by the shaft 13 outside the frame. The guidesfact also toprevent the endof the wrapper coming int-o engagement .with the rollt),on reversal of the paper, as shown in Fig. 2. As above stated, the paperand wrapper may be fed to this wrapping mechanism by hand or may beadvaneed thereto by any suitable means and the proper relative positionof the paper and wrapper secured in any manner desired, and any suitablepasting mechanism may beused for applying paste to the wrapper. In themachine, shown, however, which is especially adapted for Wrapping paperspreviously folded to wrapping size or magazines, the wrapper is lfeddownward in the path of the advancing paper and so as to be engaged uponthe proper line and carried to the wrapping mechanism by the latter, thepaste being applied to the end of the wrapper below the path of thepaper, and the papers or magazines are piled Within a holder G mountedon the front end of the machine and the bottom paper advanced from theholder to feeding belts g, h, by which they are carried to the wrappingmechanism. The upper series of belts g are led from driven feed roll- 45forvthe lower of which the belts d holder to the rolls 45, 47 and beltsg, h. Asv

shown a series of pivoted fingers 2 are used,

lthese feeding fingers being carried bya slide 50 moving on rods 5lmounted in the frame of the machine and being pressed upward so as toengage the bottom paper when withdrawn by means of springs mounted ontheslide under the fingers. This slide 50 is reciprocated upon the rods 51to advance the papers in proper time by means of slotted levers 52carried by the rock shaft 53 mounted in the' side frames, and operatedfrom shaft 54 by an eccentric 55 on said shaft and a pitman'56connecting said eccentric with one of the arms 52. The holder G is shownas adjust able so as to hold and feed papers of differentthicknesses,the rear plate 57 ofv the box being made adjustable so as toact as a stop to all the papers except the lowest and permit the passageof papers of different thicknesses, the holder'being open atl the bottomand the papers fed out by the fingers 2 over guides 58 extending fromthe box to the rolls 45, 47. From the rolls 46, 48 and tapes g, h thepapers-are fed to the rolls h, C between short guides m, between whichguides are preferably provided anti-friction rolls l over pass, aspreviously described, the friction upon the paper between the guidesthus being removed and the belts CZ aidingin feeding the'paper downward'to the rolls b, C.

IOO

The Wrappers are eut, pasted'and advanced ed two cutting and feedingrolls H to which the wrapper web y is advanced from the web roll and bywhich it is partially severed on the proper line to form a singlewrapper.. From the cutting and feeding rolls H the partially severed webis fed downward between guides 59 by feeding belts i, k extendingdownward nearly to the Wrapping mechan ism, these belts being carriedand driven by rolls 6l at their upper ends and carried by rolls 3 attheir lower ends, one of the rolls 3 being mounted upon arms 4 so astobe adj ustable to secure the desired pressure between the two seriesof belts. For the purpose of entirely severing the wrapper at the propertime, a breaking segment I is used, coaeting with the roll 62 on theopposite side of the guides 59, the segment operating to permit thewrapper to be fed downward by the tapes t', lo, and then to positivelygrip the wrapper and wholly sever it, the segment I rotating at a higherrate of speed than that at whichthe wrapper is moving, as usual in suchconstructions. The guides 59 are broken opposite the rolls 46, 4S, andguides m and then extend downward below the wrapping mechanism and thepaste is applied to the end of the wrapper at its lowest point by arotating paster e engaging a paste roll 63 running in its fountain 64.

The operating parts of the machine, with the exception of the rolls C, Dand flap turning roll b already described, are driven from the maindriving shaft S by the following n1eans:-The rolls 23 driving belts care driven from the gear 16 by an intermediate 65, and the other seriesof belts d are driven by gearing together the shaft of belt rolls 24, 27by gears 66 and by flap turning roll 12. The paster e is driven from theshaft S through gears 67 and in turn drives the fountain roll 63. Theshaft 54 is driven by gear 68 on shaft S and gear G9 on shaft 54 andfrom this gear 69 the feeding rolls 45, 47 are driven by intermediate 70and gear 71 on the shaft of the lower roll, the feeding rolls 45, 47being geared together and the breaking segment I driven from a gear 7lon the lower feeding roll 47 through intermediate 72. The shaft 13 isdriven from gear 17 through intermediates 73, a'nd gear 74 ou its shaft,and in turn drives the cutting rolls H from gear and intermediate 76.

The parts are so tin1ed,as will be seen from an inspection of thedrawings, that the rolls b, C, D and the belts c, d, are run ata higherrate of speed then the paper and wrapper feeding mechanisms, so as tosecure the rapid wrapping of the paper and its removal from the path ofthe next paper and wrapper as the latter advance.

The operation of the machineis as follows:- With the parts in theposition shown in Fig. 1, the rack E is being moved upward by theoperation of the cam grooveaupon the bowls 14, 15 and the feeding rollsC are being rolated to feed the paper and wrapper rearward or to theleft of Fig. 1, the paper having just been advanced to the rolls C, D bythe roll b coacting with the roll C, the guides f being raised out ofthe path of the paper. In the position shown in Fig. 2, the rack E hasreached its highest position,rotating the feeding rolls C, D to carrythe paper and wrapper into their extreme rearward position, and theguides f have been turned down to press against the rear end of thepaper by the cam w, so that the parts are in position for thecommencement of the reversed movement of the paper, the flap of thewrapper to be overlapped and pressed down for pasting lying over theroll B, so that, as the parts are reversed and the rear end of thepaper, becomes the leading end, returns below the roll b, the flap ofthe wrapper will be turned down upon the paper and pressed down upon thelayer of wrapper thereon, by the pressure between the rolls b, D. As theshaft 13 continues its rotation, the cam groove d acts upon the bowls14, 15, so as to carry the rackl bar E downward, thus reversing therotation of the rolls C, D, so as to feed the paper toward the front ofthe machine or to the right in Fig. 1, and the paper is guided below theroll b by the guides f, and is fed by the rolls b, D into the grasp ofthe belts c, d, the guides f being pressed down by the raised portion ofthe cam w long enough to insure the passage of the end of the paperbelow the roll b, and then released by the cam and returned by spring41. In the position shown in Fig. 3, the paper has just been received bythe belts c, d and is being advanced for delivery, the rear end of thepaper being still in contact with rolls b, D and the flap of the wrapperjust being turned overso as to be pressed down for pasting. Anotherpaper has meanwhile been delivered from the holder G and is beingadvanced by the belts g, h to the wrapping mechanism, while a wrapper yhas been fed downward into the path of the paper and the paster c isjust applying the paste to the end of the wrapper. As the operation ofthe machine continues, the wrapped paper is car ried away by the beltsc, d, and the rack bar E having been carried into its upper position isreturned by cam a so as to again reverse the movement of the rolls C, D,for wrapping another paper.

It will be understood that various modifications may be made in theconstructionshown without departing from the invention and the latter,considered broadly, is not to be limited to the particular form orarrangement of the devices shown.

The term rolls used throughout the speciiication and claims is intendedto include other equivalent feeding devices such as segments, and suchfeeding rolls or segments may be arranged and move in any suitablemanner to secure the advance and reverse movement of the paper, althougha pair of rolls or segments driven alternately in opposite directionsare preferably used.

While the invention has been described as applied in Wrapping newspapersand other publications, for which the machine shown is especiallyadapted, the invention is not thus limited, but the machine shown may beapplied in wrapping other articles, and the invention may be embodied inmachines especially adapted for such other uses. It will beunderstood,therefore, that the term paper has been used to designate thearticle to be wrapped only for convenience, and that the claims areintended to cover the constructions as applied in wrappin g otherpublications,or articles of any character in connection with which theinvention may be applied.
